There is often confusion about the differences between the various Shower Valves, Shower Trim Kits, and Shower Cartridges offered by Delta.

As a normal person, it's likely you have never really had to think about how a shower works until you have to go purchase one. There are some fairly simple things that seem very confusing at first but with a little explanation will all make perfect sense. Delta's website helps a bit but their information is scattered around and seems to be written for professionals like us rather than end users like you. They seem to assume you already know a lot about plumbing technology and after reading through their documentation we felt it seemed a bit confusing. The goal of this article will be to try and put things in layman's terms to the best of our ability. If anything is still confusing, make sure to Contact Us for additional help.

What is a Shower Faucet Trim Kit?

Tub/Shower Faucets typically contain two parts: The Trim Kit and the Valve. The Trim Kit is the part of the shower you see. It includes the Shower Handle to turn the water on and off, the Escutcheon Plate that covers the hole in the wall, the Shower Head, the Shower Arm, and the Flange. It can also include the tub spout if you are purchasing a Tub and Shower Combination Faucet. Delta Shower Faucet Trim Kits include the Shower Cartridge. Delta Trim Kits are arranged into different series based on the Cartridge they include. Monitor 14, Monitor 17, and Monitor 17T Series refer to differences in the Shower Cartridge included with the Trim Kit. We will be discussing the Cartridges more in detail later. Please refer to the image on the left to learn more about the components of a Shower Faucet Trim Kit.

What is a Shower Faucet Valve?

The second part of a Shower Faucet is the Valve. Sometimes referred to as a rough-in Valve, the Shower Valve is the part that installs in the wall and connects to the actual hot and cold water lines. The Valve is where the water from the hot and cold water lines inside your wall is mixed. Once the water has been properly mixed to a warm temperature it is ready to spray out your Shower Head for comfortable use. View the picture on the right to learn about the most common Universal Delta Shower Multi-Choice Valve. In the plumbing industry manufacturers typically make their Valves proprietary. This means Delta Trim Kits only fit Delta Valves. A Delta Trim Kit cannot be used with a different brand's Valve and a Delta Valve cannot be used with a different brand's Trim Kit. You may not mix and match different manufacturers as the Valve and Trim Kit are specifically designed to only fit each other when made by the same company.

***Note that on a Shower Only installation the Tub Spout Outlet will be plugged.

So What's the Point of selling the Valve and Trim Kit Separately?

Delta Arzo Thermostatic Control Stainless Steel Tub & Shower with Valve D541V

Well it doesn't make much sense if you have a brand new construction project. If you are building a new home, you have nothing so obviously you need both the Shower Valve and Trim Kit. If you are doing an extensive remodel where you are ripping out the walls and tile etc. you also will likely be changing things in the wall anyway so it's not such a big deal for you to change the Valve. In this case, a Shower Valve and Trim Combination is what you need.

However, some people only want to change the look or function of their shower, but DO NOT want to rip out the tile and go into the wall. This is where purchasing the Trim Kit only makes sense. You don't have to pull out the inside Valve, all you need to do is change the Trim and it looks like a brand new shower! Buying a Trim Kit only works great if you ALREADY have a DELTA VALVE installed in the wall. You can save lots of money on parts and the labor needed to change them if you simply swap out the Trim Kit.

The reason for selling the Valve and Trim Kit separately is that it enables you to upgrade the look of your bathroom or change the function of your shower without having to undergo major renovations. Delta manufacturers their Shower Valves to be universal. This means you can simply remove the Trim Kit (which installs over the tile) and switch it out. This makes renovation work much faster and less expensive.

As long as you are ok sticking with the Delta brand, your universal Delta rough-in Valve will fit any Delta Trim Kit. As mentioned above, this is the reason that the valves and trims made by different companies are not compatible. They do it on purpose to lock you into their brand. They know that once you have the Valve installed in the wall it will be very difficult to change. Rather than ripping out the wall and changing everything, they know it will be much cheaper and easier to just change the Trim. Therefore you will purchase another product from them rather than from a competitor. Judgement of this business practice aside, this makes it important that you choose a good product made by a good company because for better or worse, you will be kind of stuck with that brand. Ordering cheap imported showers from a no-name brand can have some pretty large consequences down the road if you ever decide to upgrade/change your shower.

Remember, it's not just about style and finish. With one Delta Shower Valve you can install any of their Shower Faucet Trim Kits. You can choose from any Delta Collection. You can change from a Modern design to a Traditional one. You can choose any finish offered by Delta. You can mix and match freely. But more importantly still, Delta's Universal Valve also offers you the ability to change the actual function of your Shower. For example you can change a normal Shower to a Thermostatic Shower without having to change the valve. The same valve can be used for a Shower only Installation and a Tub Shower Combination Installation.

This is because with Delta Shower Valves it is the Trim Kit that determines the function, not the Valve. This is NOT true with every manufacturer and the flexibility offered by Delta is a great benefit.

The Delta Multichoice Universal Shower Valve's biggest benefit is it's flexibility. By installing the MultiChoice rough valve first, you then can decide what type of shower you want. Whether you want to control just the temperature or keep temperature and volume controls separate for maximum flexibility, it’s not a problem. If you want the security of a pressure-balance cartridge or the precise temperature control of a thermostatic cartridge, MultiChoice Universal makes it easy. And with numerous style options for all functionalities, getting what you want has never been so simple.

Decoding Delta Valve Model Numbers

Although Delta valves are Universal, there is some confusion as they do offer several model numbers on their website. Typically the valve you want will be R10000-UNBX or R10000-UNWS. These are the most commonly used and work for 99% of people. To be thorough in this guide however, we will outline the other valves and why you might use them. They are all universal and all Delta Shower Trim Kits will fit every single one of these valves.

  • R10000-UNBX: Universal Inlets/Outlets Single Box Model
  • R10000-UNWS: Universal Inlets/Outlets with Stops
  • R10000-UNBXHF: High Flow Shower Only, cannot be used with Tub Shower Combinations
  • R10000-UNWSHF: High Flow with Stops Shower Only, cannot be used with Tub Shower Combinations
  • R10000-UNBXT: Universal Thin Wall Shower Valve
  • R10000-UNWSBXT: Universal Thin Wall Shower Valve with Stops
  • R10000-PXWS: Universal Pex Crimp Connections with UN Outlets with Stops
  • R10000-IPWS: Universal IPS Valve with Stops
  • R10000-MFWS: Universal Pex Cold Expansion with Stops with UN Outlets

All Valves feature forged brass bodies and Back-to-Back installation capabilities. They can be tested with air (200PSI) or water (300PS) without valve using a supplied test cap. Square plastic guard allows for right angle cuts. For use with Single or Dual Function Trim Kits. 1/2" Outlets and connections. Note: No tub outlet in the HF model. You should use proper the fitting with each type (copper tubing, iron pipe, and pex fitting). Make sure to use proper tooling with crimping pex fitting and cold expansion pex models. IP indicates female 1/2" threaded connections. UN indicates universal type fitting and is 1/2" NPT male thread with 1/2" CWT female sweat. Lifetime warranty on parts. Delta Valves Comply with all low lead regulations. Complies with CSA B125.1 and ASME A112.18.1.

Delta MultiChoice Universal Tub and Shower Rough-in Valve with Stops 764684

What is a Shower Valve with "Stops"?

The image to the left shows where you can find the shower stops in the Valve. Stops are unnecessary in some installations but make a lot of sense for others. Basically stops allow you to shut off the water to that specific Shower Valve but leave the water on in the rest of the house. This means if you ever need to change your Shower Trim Kit or repair a problem with that Shower Valve you will not have to shut off the water to your entire home. The stops act as a shut-off for that specific fixture.

So if you have a single family home and shutting off the water for a few hours is no big deal, shower valve stops are basically unnecessary. If however you are installing your Delta Shower in a multi-family complex like an apartment building where it would be difficult to get the building water shut off, a Shower Valve with Stops can save you a lot of hassle.

Stops are a simple open and close valve operated by a standard screw driver. Turning them shuts off the flow of water to the Shower Valve, allowing you to detach the Trim Kit or switch out a leaky cartridge.

Types of Shower Fixtures

Once you have the Universal Valve you can select any Trim Kit. Delta's Universal Shower Valve can even be used as a base for a full Delta Shower System. Different functions you can use the Universal Valve for are Tub and Shower Faucet Combinations, Shower Only Faucets, and Shower Handle Controls.

Additionally you may want to consider incorporating a Diverter into your Shower Design. Diverters USE A DIFFERENT VALVE from normal Shower fixtures as their function is different. Diverter valves do not mix water like a normal Shower Valve. They diverter already mixed water take in from the normal valve and send it to the peripheral shower systems (eg. Showerheads, Handheld Showers, or Body Sprays. The diverter valves are however all compatible with each and every style of Delta Diverter. Diverters are primarily used for when you want more than one spray option for your shower. For more information see: How to Build a Custom Shower System. If you want a more simple and less expensive solution, read more about our Easy Install Shower Systems.

Delta Shower Cartridges

In addition to the different types of Showers discussed above, you also need to consider the Cartridge. Delta's universal Valve design requires that the cartridge take on a larger role. The Cartridge will even affect overall water output. The cartridge can assist in raising your Shower's water pressure. Delta also makes cartridges that allow you to control the temperature and volume output of water separately. Their most high-end cartridge is the Thermostatic cartridge (Tempassure) which automatically adjusts the water mixture to maintain precise temperature control.

There are 3 Cartridges offered by Delta. The Cartridge is INCLUDED WITH THE TRIM KIT. When selecting a trim kit, make sure to consider the cartridge that comes with it so you will fully understand the features offered.

Delta Rough-in Valve with Cartridges

So what is the difference between the Cartridges?

First you have to understand that ultimately the roll of the cartridge is to allow you to turn on the water using the handle and to control the flow of water from the valve up to the Shower Head. The cartridge also controls the flow of water from the valve and out through the Shower Head. If you are putting together a Full Custom Shower System, it is recommended you choose a Trim Kit with a 17T Tempassure cartridge as these put out the most water. For normal use of just a Showerhead or a Tub and Shower combo, all the cartridges are fine, but there are some slight differences between them.

Single Function Pressure Balanced Valve Cartridge: Monitor 14

This item your standard normal cartridge. At 80 PSI it puts out 7.96 gallons of water per minute. This cartridge functions as a single control for temperature only. As you rotate the handle the water comes on and as you turn it counter-clockwise, the water gets warmer. You do not have independent control over the amount of water volume that comes out of your showerhead. Consistent temperature (+/- 3.6 degrees F) is achieved by balancing the pressure of both the hot and cold water. This cartridge is offered with all Monitor 13 and Monitor 14 Series Delta Tub/Showers.

Delta Dryden Champagne Bronze Large Square Shower Only Faucet with Valve D570V

Dual-Function Pressure Balanced Valve Cartridge: Monitor 17

This item adds another level of functionality to your Shower. This cartridge allows the user to control the temperature and volume of water independently. The temperature can be set in order to remain consistent shower after shower but can also be adjusted as desired. Constant temperature (+/- 3.6 degrees F) is achieved by balancing the pressures of both the hot and cold water. Dual function cartridges come in all Monitor 17 Series Delta Tub/Showers. This cartridges allows for water flow of 6.98 gallons per minute at 80 PSI.

Delta Ashlyn Chrome Finish Monitor 17 Series Shower Only Faucet with Dual Temperature and Pressure Control INCLUDES Rough-in Valve D1142V

Dual-Function Thermostatic Valve Cartridge: Monitor Tempassure 17T

These are the most high-end cartridges offered by Delta. They put out 8.53 gallons of water per minute at 80 PSI. The Thermostatic Shower Valve cartridge is Delta's newest innovation, designed to keep water temperature consistent (+/- 3 degrees F) by measuring and monitoring the temperature of the water and then automatically adjusted the water mix to maintain a more precise water temperature. This cartridge also offers separate temperature and volume control. The temperature can be set to remain constant shower after shower. It is easily adjustable if desired. Thermostatic cartridges come in all Tempassure 17T Series Delta tub/showers.

Dual-Function Thermostatic Tempassure Cartridge vs. standard Dual-Function Cartridge

So after reading the descriptions above, you may be thinking that the second and third options on the list seem awfully similar. They are quite similar but the Tempassure technology definitely offers a more luxurious shower experience. As noted above, the 8.53 GPM of the Tempassure cartridge is quite a bit more than the 6.98 GPM of the standard Dual-Function. If you are creating a Custom Shower System and want to power several Shower Sprays off of one valve, the higher water pressure can make all the difference. For more, read our in-depth explanation of the difference between the Delta Monitor 17 Series and 17T TempAssure Shower Trim Cartridges.

Tempassure technology also keeps the water within a slightly stricter range - 3 degrees vs. 3.6 degrees. That may not seem like a lot but it is actually a 20% difference, making for a fairly decent bump in the accuracy of control. The Tempassure cartridge also features an adjustable high-temperature limit stop that when properly set helps ensure the handle cannot be turned to a position that is too hot for comfort. Because the Tempassure actually measures the temperature of the water, the handle limit stop will not need to be adjusted for seasonal ground water temperature changes.

Examples of Delta Tempassure Monitor 17T Cartridge Showers:

Delta Dryden Venetian Bronze Thermostatic Shower Dual Control with Valve D1017V
Delta Cassidy Polished Nickel Thermostatic Large Tub & Shower with Valve D518V
Delta Dryden Thermostatic Stainless Steel Finish Tub and Shower with Valve D499V
Delta Dryden Dual Control Chrome Modern Thermostatic Shower with Valve D802V

Delta Monitor Faucets

When you are shopping for different cartridges, you need to pay attention to the series number of the Delta Shower Trim Kit. The Delta 1300 and 1400 Series Trim Kits include the single function cartridge. The Delta 1700 Series Trim Kits include the Dual-Function Cartridge. The 17T Series Trim Kits all come with the Dual-Function Thermostatic Valve Cartridge. Remember from before, ALL TRIM KITS USE THE SAME VALVE. This information should help illustrate just how many variations can be delivered from the same rough-in valve. This is a huge benefit to the Delta brand.

How the Monitor Technology Works

The point of the Monitor technology is that it prevents sudden and possibly unsafe changes in shower water temperature. In the old days, flushing a toilet or turning on the washing machine might change the water temperature if someone is taking a shower at the same time. Delta Monitor Faucets are designed to avert these problems.

Delta Monitor faucets feature pressure balance valves to keep water temperature in a safe +/- 3 degrees Fahrenheit range. This protects you from sudden changes in hot or cold water pressure. Monitor Faucets feature Anti-scald technology which prevents you from being burned by hot water should a change in water temperature occur. In fact, most local building codes these days require Showers to be Anti-scald in new home construction.

Monitor Faucets also feature an adjustable high-temperature limit stop that when properly set helps ensure the handle cannot be turned to a position that is too hot for comfort. This however may require seasonal adjustment unless you have a 17T series thermostatic cartridge trim kit. For more information on Delta cartridges read our guide to Delta 17 and 17T series Shower cartridges.

Delta Showers Summary

So this might feel like information overload. Here's the long and short of it. To build a Delta Shower you need a Rough-in Valve and a Trim Kit - both made by Delta. That's it. Period. Remember though, the cartridge that comes with the Trim Kit you choose does have some effect on the function of your shower so take that into consideration.

Hi Dale, unfortunately you will have to change the entire trim kit. The 17T cartridge is actually longer and significantly different so you cannot simply swap the cartridge. The good news is, you will NOT have to change the valve in the wall provided your shower valve was installed after 2006. A trim kit with a 17T series cartridge will increase your water pressure. For a detailed explanation as to why, see this article on Delta Thermostatic Shower Cartridges 17 Series vs. 17T: https://faucetlist.com/blogs/buying-guides/delta-thermostatic-shower-faucet-trim-kit-cartridges-monitor-17-series-vs-17t-series-tempassure – Because the 17 series uses pressure balancing to keep the temperature stable, you can see a drop in water pressure. The 17T series cartridges are true thermostatic and will allow maximum water pressure. Your showerhead may be a limiting factor in water pressure so you might also need to replace it. However, in the end water pressure is ultimately determined by the pressure coming into your home and if you don’t get good water pressure from the city, the shower faucet or showerhead is unlikely to fix that. Contact us if you have additional questions. Thanks

Hi, I have a Delta Lahara 17 monitor shower trim kit and cartridge. If I want to upgrade to a 17t cartridge, do I have to change the rest of the trim kit as well, or will the 17t cartridge fit in the monitor trim? And do I also have to change the shower head? I am trying to increase the water pressure.

Hi Larane, the R10000-UNBXHF has a slightly higher flow rate than the R10000-UNBX valve. The main difference is that the bottom port of the R10000-UNBXHF is permanently soldered closed so it can only be used for a shower only (and not as a tub shower combination). The “HF” in the part number stands for high-flow. Delta has designed this valve to provide a high water pressure for a complete shower system or just a normal showerhead. Keep in mind, often the valve is not what actually limits the amount of water pressure coming out of your showerhead. The showerhead itself is the primary bottleneck to water pressure. A standard Shower Valve will put out between 6-9 gallons per minute of water. However, a standard Shower Head will only allow 2.0 or 2.5 gallons per minute of water to flow through. Therefore it’s not very important which valve you use if you are only going to have a single showerhead in your shower. If you plan to have a complete shower system with multiple showerheads or body sprays, then the high-flow valve might be a better choice. Hope this helps! Thanks

Hi Michael, 58471-PK is an in2ition hand shower / shower head combination. It will work with any normal shower arm. You can use that item in your existing shower without changing anything else – you just screw it on to the shower arm. If you are planning on redoing everything, you might want to take a look at our Shower Faucets with Hand Showers category (Hover over Shower in the top menu and in the second column click “Shower Faucet with Hand Shower”. If you plan to change out everything you might want to go with one of these items. If you have any other questions please let us know! Thanks

Hi Vince, if you have a Delta R10000 series rough-in valve installed in the wall, you would be able to switch your 1400 series to a 1700 series trim kit. The key thing when it comes to Delta is that the rough-in valve is universal. It can be used with all their trim kits. Just remember, this only applies to the new style rough-in valve that was released in 2006. If you have a very old valve you will need to also upgrade the valve if you want to switch a 1400 to a 1700 trim kit. Hope this helps, if you have any questions please email sales@faucetlist.com! Thanks

Hi Tamara, “R10000-LBX” is shown on Delta’s website as an item exclusively available from Lowes. After reading through the questions on Delta’s website, it seems this item is identical to the R10000-UNBX but the packaging is different. It definitely is a little confusing but it sounds like the LBX is exactly the same as the UNBX. Hope this helps!

Hi, in 2006 Delta made a major change to their valve so it is unlikely you can use the old valve with a new trim kit. You should try calling Delta tech support to see if they can help you identify your valve. They are actually very helpful with more technical questions about specific situations. Here’s their number: 1-800-345-DELTA (3358)
